Hello, If by any chance you may have come across my other thread, I mentioned that my logic board is not working any more. After searching alot about the problem and talking to Apple Genius, I believe its more of my fault. I keep my laptop on nearly about 24hrs. Just put it in sleep mode to carry it to office and back. When at home I keep the laptop on bed and it remains switched on cauz something or the other is getting downloaded. Also I have the air condition on and off regularly which makes my room some what humid. Now i am on getting a new mac. My question is what kind of precautions shall I take? I dont want to change the habit of keeping my mac on 24hrs, so if I use a stand on bed will it matter a bit? Thank you for reading.
